Gas Turbine
A gas turbine, also called a combustion turbine, is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller ( turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission ( turboshaft), marine propeller or electrical generator (power turbine). Grea ...

Gas Turbine Applications (numbered)
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture, such as air, contains a variety of pure gases. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colourless gas invisible to the human observer. The gaseous state of matter occurs between the liquid and plasma states, the latter of which provides the upper temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention. High-density atomic gases super-cooled to very low temperatures are classified by their statistical behavior as either Bose gases or Fermi gases. For a comprehensi ...

Tank
A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong armour, and good battlefield mobility provided by tracks and a powerful engine; usually their main armament is mounted in a turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large- caliber tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than whe ...

Horseless Carriage
Horseless carriage is an early name for the motor car or automobile. Prior to the invention of the motor car, carriages were usually pulled by animals, typically horses. The term can be compared to other transitional terms, such as wireless phone. These are cases in which a new technology is compared to an older one by describing what the new one does not have. Most horseless carriages are notable for their similarity to existing horse-drawn carriages, but with some type of mechanical propulsion. Features of the first horseless carriages include tiller steering, an engine under the floorboards, and a high center of gravity. In the 19th century, steam engines became the primary source of power for railway locomotives and ships, and for powering processes in fixed installations such as factories. In 1803, what is said to have been the first horseless carriage was a steam-driven vehicle demonstrated in London, England, by Richard Trevithick. In the 1820s, Goldsworthy Gurney built ...

John Barber (engineer)
John Barber (1734–1793) was an English coal viewer and inventor. He was born in Nottinghamshire, but moved to Warwickshire in the 1760s to manage collieries in the Nuneaton area. For a time he lived in Camp Hill House, between Hartshill and Nuneaton, and later lived in Attleborough. He patented several inventions between 1766 and 1792, of which the most remarkable was one for a gas turbine. Although nothing practical came out of this patent, Barber was the first man to describe in detail the principle of the gas turbine, and in recent years a working model based on Barber's specification has been built. Barber's gas turbine In 1791 Barber took out a patent (UK patent no. 1833 – ''Obtaining and Applying Motive Power, & c. A Method of Rising Inflammable Air for the Purposes of Procuring Motion, and Facilitating Metallurgical Operations'') which contained all of the important features of a successful gas turbine. Planned as a method of propelling a "horseless carriage", Ba ...

Ferdinand Verbiest
Father Ferdinand Verbiest (9 October 1623 – 28 January 1688) was a Flemish Jesuit missionary in China during the Qing dynasty. He was born in Pittem near Tielt in the County of Flanders (now part of Belgium). He is known as Nan Huairen () in Chinese. He was an accomplished mathematician and astronomer and proved to the court of the Kangxi Emperor that European astronomy was more accurate than Chinese astronomy. He then corrected the Chinese calendar and was later asked to rebuild and re-equip the Beijing Ancient Observatory, being given the role of Head of the Mathematical Board and Director of the Observatory. He became close friends with the Kangxi Emperor, who frequently requested his teaching in geometry, philosophy and music. Verbiest worked as a diplomat, cartographer, and translator; he spoke Latin, German, Dutch, Spanish, Hebrew, Italian and Manchu. He wrote more than thirty books. During the 1670s, Verbiest designed what some claim to be the first ever self-propelled ...

Giovanni Branca
Giovanni Branca (22 April 1571 – 24 January 1645) was an Italian engineer and architect, chiefly remembered today for what some commentators have taken to be an early steam turbine. Life Branca was born on 22 April 1571 in Sant'Angelo in Lizzola. From 1616 Branca was employed at the Sacra Casa (Virgin’s Holy House) in Loreto. He was made a citizen of Rome in 1622. He died on 24 January 1645 in Loreto. Le Machine Branca designed many different mechanical inventions, a collection of which he dedicated to Cenci, the governor of Loreto, Ancona. These were later published in book form at Rome in 1629, under the title ''Le machine''. The work contains 63 engravings with descriptions in Italian and Latin and was an example of the ''Theater of machines'' genre which had appeared in the 16th century, named after Jacques Besson's ''Theatrum Instrumentorum'' of 1571. However, where Besson's book had been beautifully illustrated with engravings, Branca's book was a small octav ...

Bevel Gear
Bevel gears are gears where the axes of the two shafts intersect and the tooth-bearing faces of the gears themselves are conically shaped. Bevel gears are most often mounted on shafts that are 90 degrees apart, but can be designed to work at other angles as well. The pitch surface of bevel gears is a cone, known as a pitch cone. Bevel gears transfer the energy from linear to vertical power, making it very useful in machines widely used in mechanical settings. Introduction Two important concepts in gearing are pitch surface and pitch angle. The pitch surface of a gear is the imaginary toothless surface that you would have by averaging out the peaks and valleys of the individual teeth. The pitch surface of an ordinary gear is the shape of a cylinder. The pitch angle of a gear is the angle between the face of the pitch surface and the axis. The most familiar kinds of bevel gears have pitch angles of less than 90 degrees and therefore are cone-shaped. This type of bevel gear ...

Stamp Mill
A stamp mill (or stamp battery or stamping mill) is a type of mill machine that crushes material by pounding rather than grinding, either for further processing or for extraction of metallic ores. Breaking material down is a type of unit operation. Description A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft. As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam. Each one frame and stamp set is sometimes called a "battery" or, confusingly, a "stamp" and mills are sometimes categorised by how many stamps they have, i.e. a "10 stamp mill" has 10 sets. They usually are arranged linearly, but when a mill is enlarged, a new line of them may be constructed rather than extending the line. Abandoned mill sites (a ...

Leonardo Da Vinci
Leonardo di ser Piero da Vinci (15 April 14522 May 1519) was an Italian polymath of the High Renaissance who was active as a painter, draughtsman, engineer, scientist, theorist, sculptor, and architect. While his fame initially rested on his achievements as a painter, he also became known for his notebooks, in which he made drawings and notes on a variety of subjects, including anatomy, astronomy, botany, cartography, painting, and paleontology. Leonardo is widely regarded to have been a genius who epitomized the Renaissance humanist ideal, and his collective works comprise a contribution to later generations of artists matched only by that of his younger contemporary, Michelangelo. Born out of wedlock to a successful notary and a lower-class woman in, or near, Vinci, he was educated in Florence by the Italian painter and sculptor Andrea del Verrocchio. He began his career in the city, but then spent much time in the service of Ludovico Sforza in Milan. Later, ...

Smoke Jack
A roasting jack is a machine which rotates meat roasting on a spit. It can also be called a spit jack, a spit engine or a turnspit, although this name can also refer to a human turning the spit, or a turnspit dog. Cooking meat on a spit dates back at least to the 1st century BC, but at first spits were turned by human power. In Britain, starting in the Tudor period, dog-powered turnspits were used; the dog ran in a treadmill linked to the spit by belts and pulleys. Other forms of roasting jacks included the steam jack, driven by steam, the smoke jack, driven by hot gas rising from the fire,''By J. Wilkins, late Ld BP of Chester.
